Bearing arrangement with two in the mutual axial spacing between the rotor and the fixed housing of a differential gear bearing of the rolling-type arranged

摘要

An automotive differential has a differential case or rotor (20) rotatably mounted in a differential carrier (10) by a pair of spaced anti-friction bearings (30). The axial position of each of the anti-friction bearings is adjustable by virtue of a semi-cylindrical bearing retainer cap (40) which has an outer end face (40a) engaging an internally projecting shoulder (10c) in the stationary differential carrier and is provided with axially elongated slots (40c) for reception of mounting bolts (41) which engage threaded holes provided in the carrier adjacent a semi-cylindrical bore (10a) therein which functions as the other half of the bearing housing and which is machined with the bearing retainer in assembled position, thus permitting precise axial location of the bearing to permit axial positioning of the differential rotor relative to the carrier by a few shims (50) or an adjusting washer (60) to eliminate end play therebetween.
